By generalizing the notion of location of a constituent to allow discontinuous Ioctaions, one can describe the discontinuous constituents of non-configurational languages. These discontinuous constituents can be described by a variant of definite clause grammars, and these grammars can be used in conjunction with a proof procedure to create a parser for non-configurational languages. are explicitly represented in the grammar formalism. Given this, it will be easy to generalize the notion of location so that it can describe the discontinuous constituents of non-configurational languages. .
